To all whom it may concern:

Be it known that I, Gnonon K. Acrnmson,

a citizen of the United States, and a resident of the city ofl lew York, borough of Brooklyn, county of KingmEtate of New York, have invented a new and Improved Drillinglil lachine, of which the following is a full, clear, and exact description.

The present invention relates to newand useful improvements in drilling machines, and it pertains more particularly to drilling machines of the vertical spindle type.

The primary object of the invention is to provide a machine of this character in which all of the moving parts are inclosed, thus protecting them from dust, dirt and the like, and, at the same time, affording protection against injury to the operator of the machine.

A further object of the invention is to construct a machine of this character in such a manner that all of its parts are readily accessible.

VVith the above and other objects in view, reference is had to the accompanying drawin s, in which- *igure 1 is a side elevation of a machine constructed in accordance with the present invention Fig. 2 is a front elevation thereof; and

Fig. 3 is a top plan view of the base.

Referring more particularly to the drawings, the reference character 5 designates a base, and secured thereto by means of bolts or the like 6, is a box or housing 7, which is adapted to inclose a spced-changing mechanism, not shown. Secured to the upper face of the box or housing 7, is a driving motor 8, and surrounding the gears, not shown, of said motor and the shaft leading to the box or housing 7, is a guard 9.

Secured to the base 5, by means of bolts 10, is a vertically extending supporting standard 11, said standard being preferably tubular in form. This standard is provided on its upper end with integral projecting cars 12, the purpose of which will be hereinafter described.

The reference character 13 designates a yoke, which surrounds the vertically extending supporting standard 11, and formed integral with said yoke 13, is a forwardly projecting bracket 14, upon which is adjustably carried a work-supporting table 15. This work-supporting table 15 has a depending shaft 16, which is received within a circular opening in the forward endof the bracket, this mechanism forming the means by which the work-supporting table is movably mounted relative to the bracket 14.

Projecting vertically from the rear portion of the base 5, is a tubular member 20, and said tubular member is connected with the vertical work-supporting standard 11,.

by a transversely extending brace 21. The upper end of this tubular member 20 is pro vided with a flange 22, the purpose of which will be hereinafter described. Secured to the base 5, by screws or bolts 23, is a brace 21, the other end of which is suitably connected to the vertical tubular member 20, near its lower end.

The reference character 25 designates a transmission housing, and said transmission housing comprises two half sections secured together by means of bolts or the like 26. This transmission housing is substantially rectangular in form and is provided near its rear end with a tubular projecting portion 27, which is adapted to rest upon the hereto-fore mentioned flange 22, and receive the upper end of the tubular member 20, as best shown in Fig. 1.

Intermediate of its ends, the lower section of the transmission housing is provided with a depending tubular member '28, which tubular member is provided with a plurality of lugs 29. These lugs 29 are so positioned as to register withthe lugs 12 of the vertical supporting standard 11, in order that secur ing bolts 30 may be positioned to retain the transmission housing in place on the upper end of the vertical supporting standard 11. Formed integral with the lower half section of the transmission housing 25, at its forward end, is a clutch housing 82, and pr0- jecting through the transmission housing is the vertical spindle 33 of the machine.

The reference character 34; designates an adjustable bracket which mounted on a guide 35 on the front supporting bracket 11, and mounted. in the forward end of said bracket 34:, is a sleeve 36, which in turn sursupporting standard projecting from said 15; I standard to support said gear housing, the

other section of said gear housing being restated, means by which the moving parts may be inclosed for the I claim: 7 1. In a drilling machine, a base, a tablepurposes set forth.

base, a divided gear housing, one section of which is provided 'wlth a depending tubular extensionadapted to be removably secured to the upper end of the table-supporting movably secured to the first-mentioned section, and a shaft-inclosing housing, said shaft-inclosing housing projecting from the base to the first-mentioned section of the gear housing, substantially as described.

2. In a drilling machine, a base, a tablesupporting standard removably secured to the base and projecting vertically therefrom, a divided gear housing, one section of which is provided With an integral tubular depending extension adapted to be reinovably securedto the upper end of said table-supporting standard to form the support of the gear housing, and a shaft-inclosing housing, said housing extending aarallel with the tablesupporting standard and connected thereto by means of a laterally projected extension formed integral with the shaft housin GEORGE K.
